  Background and Objectives: Urinary tract infections (UTI) are the most common bacterial diseases in humans which it has been reported to involve between 30-50% of population according to current statistics. The indiscriminate use of antibiotics increases the resistance to treatment of urinary tract infections. This study was designed to detect the bacterial causing agents in urinary tract infections in patients referred to Razi laboratory in Babol (Iran) during 2 years.

  Materials and Methods: This cross- sectional study was carried out on total of 14320 urine samples during the years (2008-2009). After the culture and diagnostic of bacterial agents , antimicrobial pattern testing was performed by disk diffusion method according to NCCLS standards.

  Results: Amoung 14320 samples, 770 (5.4%) patients had positive cultures. The most common cause of urinary tract infections were E.coli (48.6%), Kelebsiella (17.9%) and Enterobacter (17.1%) respectively. Drug susceptibility assay revealed that ciprofloxacin was the most sensitive antibiotic agent and ampicillin was the most resistant antibiotics.

  Conclusion: Our study showed that gram-negative bacilli, especially Ecoli is dominant bacterial agents that causes urinary tract infections in this region . Most isolated species showed a high resistance to common antibiotics like Ampicillin.

  Key words: Urinary tract infections, Bacterial agents, Antibiotics, Resistance

  Funding: This study did not have any sources of funding. 

  Conflict of interest: None declared.

  Ethical approval: The Ethics committee of Babol University of Medical Sciences approved the study.
